Send touch mode state to input

WindowManager remains the source of truth of the touchmode state.
However, we need to keep a copy of this state in input.

The apps determine the touch mode state. Therefore, a single app will
affect the global state. That state change needs to be propagated to
other apps, when they become focused.

If the input dispatches focus to the apps instead of the WindowManager,
input needs to keep a copy of the touch mode state.

Since the touch mode state changes infrequently, this should not have
performance impact.
